How to create XMPP chat client for facebook?
Solution 1
to get access token first you have to login
fb.authorize(FacebookActivity.this, new String[] {"xmpp_login"},Facebook.FORCE_DIALOG_AUTH, new DialogListner());
SASLXFacebookPlatformMecha class
import java.io.IOException;
import java.net.URLEncoder;
import java.util.GregorianCalendar;
import java.util.HashMap;
import java.util.Map;
import org.apache.harmony.javax.security.auth.callback.CallbackHandler;
import org.apache.harmony.javax.security.sasl.Sasl;

public class SASLXFacebookPlatformMecha extends SASLMechanism {
private static final String NAME = "X-FACEBOOK-PLATFORM";
private String apiKey = "";

/**

*/
public SASLXFacebookPlatformMecha(SASLAuthentication saslAuthentication) {
super(saslAuthentication);
}
@Override
protected void authenticate() throws IOException, XMPPException {
getSASLAuthentication().send(new AuthMechanism(NAME, ""));
}
@Override
public void authenticate(String apiKey, String host, String acces_token)
throws IOException, XMPPException {
if (apiKey == null || acces_token == null) {
throw new IllegalArgumentException("Invalid parameters");
}
this.access_token = acces_token;
this.apiKey = apiKey;
this.hostname = host;
String[] mechanisms = { NAME };
Map<String, String> props = new HashMap<String, String>();
this.sc = Sasl.createSaslClient(mechanisms, null, "xmpp", host, props,

authenticate();
}
@Override

authenticate();
}
@Override
protected String getName() {
return NAME;
}
@Override
public void challengeReceived(String challenge) throws IOException {
byte[] response = null;
if (challenge != null) {
String decodedChallenge = new String(Base64.decode(challenge));
Map<String, String> parameters = getQueryMap(decodedChallenge);
String version = "1.0";
String nonce = parameters.get("nonce");
String method = parameters.get("method");
long callId = new GregorianCalendar().getTimeInMillis();
String composedResponse = "api_key="

+ "&access_token="
+ URLEncoder.encode(access_token, "utf-8") + "&v="
+ URLEncoder.encode(version, "utf-8");
response = composedResponse.getBytes("utf-8");
}
String authenticationText = "";
if (response != null) {
authenticationText = Base64.encodeBytes(response,
Base64.DONT_BREAK_LINES);
}
// Send the authentication to the server
getSASLAuthentication().send(new Response(authenticationText));
}
private Map<String, String> getQueryMap(String query) {
Map<String, String> map = new HashMap<String, String>();
String[] params = query.split("\\&");
for (String param : params) {
String[] fields = param.split("=", 2);
map.put(fields[0], (fields.length > 1 ? fields[1] : null));
}
return map;
}
}
I created ChatManager class
import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ChatManagerListener;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterListener;
import org.jivesoftware.smack.SASLAuthentication;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Presence;
import org.jivesoftware.smack.packet.Presence.Type;
import org.jivesoftware.smackx.pubsub.PresenceState;
public class FacebookChatManager {
private static FacebookChatManager chatManager;
private XMPPConnection connection;
private final String SERVER = "chat.facebook.com";
private final int PORT = 5222;
private final String FACEBOOK_MECHANISM = "X-FACEBOOK-PLATFORM";
private RosterListener rosterListner;
private FacebookChatManager(RosterListener rosterListner)
{
this.rosterListner = rosterListner;
ConnectionConfiguration connFig = new ConnectionConfiguration(SERVER,
PORT);
connFig.setSASLAuthenticationEnabled(true);
connection = new XMPPConnection(connFig);
//setup facebook authentication mechanism
SASLAuthentication.registerSASLMechanism(FACEBOOK_MECHANISM,
SASLXFacebookPlatformMecha.class);
SASLAuthentication.supportSASLMechanism(FACEBOOK_MECHANISM, 0);
}
public static FacebookChatManager getInstance(RosterListener rosterListner)
{
if(chatManager == null)
{
chatManager = new FacebookChatManager(rosterListner);
}
return chatManager;
}
public boolean connect()
{
try {
connection.connect();
return true;
} catch (XMPPException e) {
e.printStackTrace();
connection.disconnect();
}
return false;
}
public void disConnect()
{
connection.disconnect();
}
public boolean logIn(String apiKey, String accessToken)
{
try {
connection.login(apiKey, accessToken);
setPresenceState(Presence.Type.available, "");
connection.getRoster().addRosterListener(rosterListner);
return true;
} catch (XMPPException e) {
connection.disconnect();
e.printStackTrace();
}
return false;
}
public Roster getRoster()
{
return connection.getRoster();
}
public Chat createNewChat(String user, MessageListener messageListner)
{
return connection.getChatManager().createChat(user, messageListner);
}
public void registerNewIncomingChatListner(ChatManagerListener chatManagerListner)
{
connection.getChatManager().addChatListener(chatManagerListner);
}
public void setPresenceState(Type precenseType, String status)
{
Presence presence = new Presence(precenseType);
presence.setStatus(status);
connection.sendPacket(presence);
}
public Presence getUserPresence(String userId)
{
return connection.getRoster().getPresence(userId);
}
}
at the end to use that FacebookChatManager class note that rosterListnr is used to get info about your friends state change implement one as you want
FacebookChatManager facebookChatManager = FacebookChatManager.getInstance(rosterListner);
if (facebookChatManager.connect()) {
if (facebookChatManager.logIn(FacebookActivity.APP_ID,
access_token)) {
return facebookChatManager.getRoster();
}
}
Solution 2
You need an access token. http://developers.facebook.com/tools/access_token/

I'm creating XMPP client for FACEBOOK. i did this for gmail, now i have to create same for FaceBook. i googled a lot for this got some code, still i'm getting this type of errors
Not connected to server
andservice-unavailable(503)
here i'm sharing the code what i did.
public class ClientJabberActivity extends Activity { ArrayList<String> m_discussionThread; ArrayAdapter<String> m_discussionThreadAdapter; XMPPConnection m_connection; private Handler m_handler; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); m_handler = new Handler(); try { initConnection(); } catch (XMPPException e) { e.printStackTrace(); } final EditText recipient = (EditText) this.findViewById(R.id.recipient); final EditText message = (EditText) this.findViewById(R.id.message); ListView list = (ListView) this.findViewById(R.id.thread); m_discussionThread = new ArrayList<String>(); m_discussionThreadAdapter = new ArrayAdapter<String>(this, R.layout.multi_line_list_item, m_discussionThread); list.setAdapter(m_discussionThreadAdapter); Button send = (Button) this.findViewById(R.id.send); send.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { String to = recipient.getText().toString(); String text = message.getText().toString(); Message msg = new Message(to, Message.Type.chat); msg.setBody(text); m_connection.sendPacket(msg); m_discussionThread.add(" Me : "); m_discussionThread.add(text); m_discussionThreadAdapter.notifyDataSetChanged(); } }); } private void initConnection() throws XMPPException { ConnectionConfiguration config = new ConnectionConfiguration( "chat.facebook.com", 5222, "chat.facebook.com"); config.setSASLAuthenticationEnabled(true); m_connection = new XMPPConnection(config); try { SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM", SASLXFacebookPlatformMechanism.class); SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0); m_connection.connect(); m_connection.login(apiKey + "|" + sessionKey, sessionSecret, "Application"); } catch (XMPPException e) { m_connection.disconnect(); e.printStackTrace(); } Presence presence = new Presence(Presence.Type.available); m_connection.sendPacket(presence); PacketFilter filter = new MessageTypeFilter(Message.Type.chat); m_connection.addPacketListener(new PacketListener() { public void processPacket(Packet packet) { Message message = (Message) packet; if (message.getBody() != null) { String fromName = StringUtils.parseBareAddress(message .getFrom()); m_discussionThread.add(fromName + ":"); m_discussionThread.add(message.getBody()); m_handler.post(new Runnable() { public void run() { m_discussionThreadAdapter.notifyDataSetChanged(); } }); } } }, filter); ChatManager chatmanager = m_connection.getChatManager(); chatmanager.addChatListener(new ChatManagerListener() { public void chatCreated(final Chat chat, final boolean createdLocally) { chat.addMessageListener(new MessageListener() { public void processMessage(Chat chat, Message message) { System.out.println("Received message: " + (message != null ? message.getBody() : "NULL")); Log.i("CHAT USER", "Received message is: " + message.getBody()); } }); } }); } }
and this class SASLXFacebookPlatformMechanism
How can i login like this
xmpp.login(apiKey + "|" + sessionKey, sessionSecret, "Application");
i know how to get acessToken, Application Key for facebook. i don't know about sessionKey, sessionSecret how to get those values and how to solve this problem.If i use
xmpp.login(apiKey, accessToken, "Application");
i am getting this error --IllegalArgumentException: API key or session key is not presentEDIT: Finally i got solution from Amal solution :
xmpp.login(apiKey, accessToken, "Application");
